Ukulayisha ukulayisha Kusetshenziswa kakhulu ekuncibilikiseni nasekushisiseni izinsimbi ezingenayo ayoni kanye nensimbi.Okufana ne-cast iron in smelters, insimbi evamile, ipuleti lensimbi engagqwali, i-alloy steel, ithusi, i-aluminium, igolide, isiliva ne-aluminium alloy, njll.;Izingxenye zensimbi nezethusi zokubumba i-diathermy, izingothi ze-aluminium zokubunjwa kwe-extrusion, njll. Yenza ukwelapha kokucisha nokomisa okufana nokwelapha ukushisa nokwelashwa kokushisa ezintweni zensimbi.Idivayisi yokushisisa isithando somlilo esiphakathi incane ngosayizi, ilula ngesisindo, iphezulu ngokusebenza kahle, ihamba phambili ngekhwalithi yokucubungula okushisayo, futhi ivumelana nemvelo.Isizukulwane esilandelayo semishini yokushisisa yensimbi yokuqeda ngokushesha iziko ezibaswa ngamalahle, iziko legesi, iziko likawoyela, neziko ezijwayelekile zokumelana nezimo.
Layisha izici ze-harmonic;Iziko lokuncibilikisa imvamisa emaphakathi zisetshenziswa kakhulu ekuncibilikiseni, ekubumbeni nakwezinye izimboni.Kodwa-ke, lapho usebenza, isithando somlilo sikagesi esiphakathi nendawo samukela ubuchwepheshe bokulungisa kanye ne-inverter, okuholela enanini elikhulu lama-harmonics amanje kanye ne-voltage.Ukungcoliswa kwe-Harmonic ohlelweni lokuphakelwa kwamandla kwenza amathuluzi anembayo asebenze ngenqubo yephutha futhi kwandisa ukulahleka kwempahla yokuphakelwa kwamandla.Uhlelo lukagesi lwesithando somlilo esiphakathi nendawo siwumthombo wamanje we-pulse omkhulu ohlelweni lokuphakela amandla, futhi ngokuvamile kukhona ukunikezwa kwamandla okushintshwa kweziko lokungeniswa kwefrikhwensi emaphakathi kanye neziko lokungeniswa kwefrikhwensi ephezulu.Ngokuvamile, izithando zomlilo ezi-6 ze-single-pulse intermediate intermediate frequency induction ikakhulukazi zikhiqiza i-harmonic yesici sezikhathi ezingu-5, 7, 11, kanye ne-13.Kufurnaces ye-12 ye-single-pulse converter intermediate frequency induction, ama-harmonics abalulekile yi-harmonics ye-11, 13, 23 kanye ne-25.Ngokuvamile, ama-pulses angu-6 asetshenziselwa imishini yokuguqula encane, ama-pulses angu-12 asetshenziselwa umshini wokuguqula omkhulu, njenge-Y/△/Y uhlobo lwe-furnace transformer, noma iziguquli zesithando somlilo ezi-2 zisetshenziselwa uhlelo lokuphakela amandla.
Ngokusho kwezinkinga ezihlangatshezwana nemisebenzi engokoqobo, okuqukethwe komswakama we-harmonic kwesithando somlilo esiphakathi kungaphansi kwama-85%, kodwa imikhiqizo yokugcinwa kwesistimu ilawulwa kakhulu yi-harmonics, ukuthuthukiswa kwama-harmonics kungashaywa indiva, futhi umphumela wokonga amandla akugculisi.Okubi nakakhulu ukuthi amandla e-harmonic adlula kude uhla oluvumelekile lwemishini yokonga amandla neyokuvikela imvelo, futhi kulula ukonakala ngemva kokusetshenziswa isikhathi eside, futhi izingozi zenzeka njalo.Ngakho-ke, ekuphenduleni isifiso esiphuthumayo semikhiqizo eminingi yokugcina, ukuvikelwa kwemvelo kanye nokonga amandla okushisa okuphakathi nendawo kuye kwaba inkinga yesikhathi eside embonini yokusetshenziswa kwamandla, okudida izimboni eziningi namabhizinisi.
1. Isithando somlilo esiphakathi nendawo sikhiqiza inani elikhulu lama-harmonics ngesikhathi sokusetshenziswa, futhi ukungcoliswa kwe-harmonic kugridi yamandla kuba kubi kakhulu.
2. I-Harmonics izonciphisa ukusebenza kahle kokudluliswa kwamandla kanye nokusetshenziswa, ukushisa kakhulu okokusebenza kukagesi, ikhiphe ukudlidliza nomsindo, i-insulation ewohlokayo, inciphise ukuphila, ngisho nokungasebenzi kahle nokusha.
3. I-Harmonics izobangela i-resonance yasendaweni kanye nokuzwakala kochungechunge lwesistimu yamandla,
4. Khulisa okuqukethwe kwe-harmonic, ushise imishini yesinxephezelo ye-capacitance nezinye izinto zokusebenza;
5. I-Harmonics idala ukuvikelwa kokudluliselwa kwedatha kanye nokungasebenzi kahle kwedivayisi;
5. Ngaphandle kwesistimu yamandla, ama-harmonics aphazamisa kakhulu imishini yokuxhumana nemishini kagesi.
6. Uma isici samandla singahlangabezani nemithethonqubo ka-0.90 yesikhungo sokuphakelwa kukagesi, inhlawulo yokulungisa imali kagesi izobekwa.
7. Isici samandla aphansi esithandweni somlilo esiphakathi kwe-frequency induction kanye nenani elikhulu lomthwalo osebenzayo ohlinzekwa yi-transformer ekhethekile ukwandisa umthwalo ku-transformer.
8. Kukhona futhi isimo: isici samandla samanye amakhasimende esitofu se-intermediate induction induction asiphansi uma sisetshenziswa, futhi sidinga kuphela ukulawula i-pulse current.
Ngakho-ke, ukuthuthukisa ikhwalithi yamandla yesithando somlilo esiphakathi kube ukhiye wempendulo.Izixazululo ongakhetha kuzo:
uhlelo 1
Ukuphatha okumaphakathi (faka izihlungi ze-harmonic egumbini lokusabalalisa amandla elifanele ukusebenza kanyekanye kweziko likagesi eliyimvamisa ephakathi nendawo)
1. Sebenzisa igatsha lokulawula i-harmonic (5, 7, 11 filter) + igatsha lokulawula amandla asebenzayo.Ngemuva kokuthi idivayisi yesinxephezelo sesihlungi isiqalile ukusebenza, isilawuli se-harmonic nesinxephezelo samandla asebenzayo wesistimu yokuphakelwa kwamandla kuhlangabezana nezimfuneko.
2. Yamukela isihlungi esisebenzayo (susa ukuhleleka kwama-harmonics ashukumisayo) kanye nesekethe yegatsha le-harmonic countermeasure (5, 7, 11 isihlungi se-oda) # + isifunda segatsha sokulungiswa okungavumelekile, futhi ngemva kokunikeza imishini yesinxephezelo yesihlungi, faka isicelo sesinxephezelo esingavumelekile uhlelo lokuphakela amandla.
Isimo 2
Ukuphathwa kwesayithi (setha idivayisi yokuhlunga ye-harmonic esizeni ene-oda eliphezulu eduze kwephaneli yamandla yesithando somlilo esimaphakathi)
1. Yamukela i-anti-harmonic bypass (isihlungi sesi-5, sesi-7, se-11), ulandelele ngokuzenzakalelayo ukusebenza kwesithando somlilo esiphakathi, ukuxazulula i-harmonics esizeni, futhi ungaphazamisi ukusebenza kweminye imishini ngesikhathi sokukhiqiza, futhi ama-harmonics awafinyeleli. izinga ngemuva kokusetshenziswa.
2. Yamukela isihlungi esisebenzayo (iyunithi yokulungisa umkhawulokudonsa) kanye nesekethe yokudlula isihlungi (isihlungi sesi-5, sesi-7), ama-harmonics we-oda eliphezulu ngemva kokuvula awafinyeleli ebhentshini.
Inketho 3:
Ifaka isihlungi sethu samandla asebenzayo athuthukisiwe anamandla amakhulu.Amandla ethu we-Hongyan APF azimele yedwa ano-100A, 200A, 300A, 500A nezinye izincazelo, futhi amayunithi ayi-6 angahambisana.Iphatha ukubambisana kwawo wonke amapheya efrikhwensi.
